The Effects of Mild Concussions and Pomegranates on Behavior

The neuropathological effects of mild concussions can accumulate, leading to the development of motor and cognitive deficits. Although there are currently no treatments that can restore lost function after repetitive concussion, our laboratory has shown that dietary supplementation with pomegranate polyphenols can improve Alzheimer’s-like pathology, protect mice from the effects of proton irradiation, and protect humans from post-operative cognitive deficits. This study investigated the behavioral and neuropathological effects of repetitive concussions in mice and the use of dietary supplementation with pomegranate to ameliorate these effects. Adult mice were given dilute pomegranate juice or control water for 1 week, followed by anesthesia, repeated anesthesia (3 days apart), or repeated concussive injury (a single closed-head injury to each hemisphere 3 days apart). They were then maintained on the pomegranate juice or control water for 2 additional weeks. Behavioral testing was administered 1, 3, 5, and 7-11 days post injury to assess cognitive, motor, and affective functions. Repeated concussion, but not repeated anesthesia, induced motor and learning deficits, some of which were significantly reduced by pomegranate juice. These data suggest that the model of mild repeated concussive injury in mice might be used to test neuroprotective treatment in future studies

StemNet: An Evolving Service for Knowledge Networking in the Life Sciences

Up until now, crucial life science information resources, whether bibliographic or factual databases, are isolated from each other. Moreover, semantic metadata intended to structure their contents is supplied in a manual form only. In the StemNet project we aim at developing a framework for semantic interoperability for these resources. This will facilitate the extraction of relevant information from textual sources and the generation of semantic metadata in a fully automatic manner. In this way, (from a computational perspective) unstructured life science documents are linked to structured biological fact databases, in particular to the identifiers of genes, proteins, etc. Thus, life scientists will be able to seamlessly access information from a homogeneous platform, despite the fact that the original information was unlinked and scattered over the whole variety of heterogeneous life science information resources and, therefore, almost inaccessible for integrated systematic search by academic, clinical, or industrial users
